A device used in radiation therapy for cancer contains 6.30×10-1 g of cobalt 2760Co (59.9333819 u). Determine the activity of the radioactive material
A body of mass M is at rest. It suddenly explodes into three pieces. One mass is .25M, moves due east at 12m/s. Find the velocity of the remianing piece
Find out the velocity with which he strikes the water. (Hint: When the diver reaches the water, his displacement is y = -3 m (measured from the board), assuming that the downward direction is chosen as the negative direction.)
A geologist searching for oil finds that the gravity at a certain location is 8 parts in 107 smaller than average. Estimate the size of the deposit
If a flea can jump straight up to a height of 22.0 , what is its initial speed as it leaves the ground, neglecting air resistance?
A car starts from rest and accelerates at a constant rate of 3.00 m/s^2 until it is moving at 18.0 m/s. The car then decreases its acceleration to 0.500 m/s^2 and continues moving for an additional 250 m. Find the total time taken.
